That is not the idea.
The idea is pointing the condom as a maximum security prison where you cannot escape.
If the personification itself was the idea, it would be the same if they were in prison, in the disco or on the beach.
The personification is just a side thing to make it all fun, likable to watch and alive. You could make the same idea as a photographic photo of a prison shaped as a condom. But it would suck.

a prison as a condom do not suck to me.
i think the personification it is a part of the idea, not the way to do it.
perhaps we should think about how they thought, if they thought on the concept and how to develop it or just thought "sperm prisoners"
excuse my english
